BURNER.

SPECIFICATION forming part of Letters Patent No. 613,921, dated November8, 1898. Application filed August 22,1898. fierial No. 689,222. (Nomodel.)

To all whom it may concern: 1

Be it known that I, HABRY M. HAMRIO K,a citizen of the United States,residing in the city and county of'Philadelphia, State of Pennsylvania,haveinvented a new and useful Improvement in Burners, which improvementis fully set forth in the following specification and accompanyingdrawings.

My invention consists in an improvement in burners in which I employ atube having a substantially continuous series of openings in theperiphery thereof for the exit of flame, said tube having a generatorsurrounding said openings, whereby flame is caused to impinge onsubstantially every portion of the adjacent surface of said generator,whereby the hydrocarbon is converted into vapor or gas and the sameconducted to a chamber and thence into the burner-tube, said generatorbeing located in proximity to openings through which flames have theirexit, Whereby substantiallyevery portion of said generator is heated toa high degree.

It further consists of novel details of construction, all as will behereinafter set forth.

Figure 1 represents an elevation of aburner embodying my invention. Fig.2 represents a vertical sectional view on line as 09,,Fig. l. V

Fig. 3 represents an elevationof a cap employed, showing perforationstherein. Fig. 4 represents a vertical sectional view of a portion of thetube employed without the use of the cap.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates the burner, the same consistingof a tube B, having in the present instance the flaring end 0 and havingthe bars D, which are suitably secured to said tube and to the casing orplug E, which latter is screw-threaded in order to be secured to theplace of support and is provided with a chamber F, having the outlet orpassage G leading therefrom. H designates a cap which is adapted to beplaced on the upper end of said tube B, between which and said cap aresituated the screens or gauzes J, said cap having slots K above saidscreens and being provided at or near its mouth with a screen or gauzeL, said screens being held in position by any suitable means.

generator-tube N, which is adjacent to said tube and passes up the sameand has a lateralportion N which serves as a generator proper and passesaround the cap H at about a level with the slots K, through which theflame is adapted to pass and heat said generator, which serves toconductthe heat to the plug E, since said generator is extended down said tubeand communicates with the chamber F in the plug E.

Y designates a screen-which is placed around the cap and covers theperforations or slots, so that the flame which issues therethrough maybe steadied.

A suitable pin-valve Q or analogous device is conveniently situated inorder to control the supply of hydrocarbon, as desired.

In lieu of the slots L in the cap H, I may employ the perforations R,the efiect being the same, and'I may dispense with said cap H and seatthe screens J directly within the tube B, (seen in Fig. 4,) in whicheventI will provide perforations S in the tube B, above said screens,andabove said perforations will be placed the gauze or screen L, theeffect being the same.

V designates a mantle which is supported above the burner by the rod orbar W, which is removably supported in a lug A by a setscrew B.

The operation is as follows: The hydrocarbon passes through the tube Minto the generator-tube N, the amount being adjusted by the valve Q, andpasses up to the generator N and around the same, where, the burnerhaving been lighted, flames will play against the generator and thehydrocarbon will be converted into vapor or gas and passes down fromthegenerator into the chamber F, from which it is forced through the outletG and into the tube B, where it mingles with the air and passes throughthe screens and is ignited.

The screen L serves to cushion enough of the flame to be thrown throughthe openings in the cap.

readily had and the same replaced if worn or broken, and this is thepreferred form; but, as above stated, the screens may be placed directlyin the tube and the cap dispensed with.

By employment of the screens L and J in conjunction with the openingssurrounded by the gauze Y it will be apparent that no pulsations willoccur and the flame will burn evenly and steadily under all conditions.

It will of course be evident that various changes may be made in theconstruction without departing from the spirit of my invention, and I donot therefore desire to be limited in every instance to the form asherein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a burner the combination of a tube having a substantiallycontinuous series of openings therein through which flame is adapted topass and a generator surrounding said tube and located in proximity tosaid openings whereby flames are caused to impinge on substantiallyevery portion of the adjacent surface of said generator.

2. In a burner, a tube having a substantially continuous series ofopenings therein, a generator surrounding said tube, and located inproximity to said openings and means for forcing a flame against saidgenerator,

said openings permitting said fiame to impinge on substantially everyportion of the adjacent surface of said generator.

3. In a burner, a tube having openings therein, a screen covering saidopenings, a generator adjacent said openings and means for forcingflames against said generator, said screen being located intermediatesaid generator and openings.

4. In a burner, a tube having a substantially continuous series ofperforations or openings in the periphery thereof, a generatorsurrounding said tube, and located in proximity to said openings, achamber communicating with said generator and a screen above saidopenings whereby a flame is projected against substantially everyportion of the adjacent surface of said generator.

5. In a burner, a tube, a cap therefor having openings therein, a screenabove said openings, a screen below said openings, a generatorsurrounding said openings,and a chamber with an outlet in communicationwith said generator.

6. In a burner, a tube, a chamber with an outlet below said tube, a capfor said tube having openings in the side, screens above and below saidopenings, a generator passing upward and around said cap in proximity tosaid openings and down and communicating with said chamber and means forregulating the supply of hydrocarbon.

7. In a burner, a tube, a chamber for the reception of the hydrocarbon,a substantially continuous series of openings in said tube through whichflame is adapted to pass, a generator surrounding said tube and locatedin proximity to said openings whereby flame is caused to impinge uponsubstantially every portion of said generator and a pipe leading fromsaid generator to said chamber.

8. In a burner, the combination of a tube having a substantiallycontinuous series of openings therein, through which the flame isadapted to pass, a generator surrounding said tube and located inproximity to said openings, said flame impinging upon substantiallyevery portion of the adjacent surface of said generator and a mantlesupported above said tube.

9. In a burner the combination of a tube having openings therein throughwhich flame is adapted to pass a generator surrounding said openings,and a gauze or screen interposed between said openings and generator.
